![]() ![]() One way that Swift assists us in achieving that sort of simplicity is through the way structs work - specifically how their memberwise initializers enable us to easily create a new instance of a given type without requiring any custom logic. ![]() After all, the way an object or value is created often acts as our very first impression of its API - so making that process as simple and as easy to understand as possible is definitely important. The simplicity of structsĪrguably one of the most significant characteristics that we’re looking for in an initializer is simplicity. What characteristics should an initializer ideally have, and what sort of techniques and patterns could be useful in order to keep our initializers simple and predictable? Let’s dive right in. We'll share the building blocks of a macro, show you how to test it, and take you through how you can emit. Code along as we explore how macros can help you avoid writing repetitive code and find out how to use them in your app. This week, let’s take a look at one of the core aspects of object-oriented programming - initialization, which is the act of preparing an object or value for use. Discover how you can use Swift macros to make your codebase more expressive and easier to read. ![]() Although Swift’s overall design incorporates several distinct programming paradigms, and makes it possible to write code using many different styles, it’s still substantially rooted in the object-oriented world.įrom the way objects and values are constructed, to how inheritance and references still play a huge role in how Apple’s frameworks are designed, object-oriented concepts are a key part of Swift - even though they are often mixed with influences from other paradigms, such as functional programming. ![]()
